- Works with Perma-Shield Narroline Double-Hung Window manufactured from 1968 to Present.
- This is a service part to replace the bottom rail foam weatherstrip when the foam weatherstrip will not make good contact with the window sill.
- Use Andersen's recommended clear silicone to adhered weatherstrip to bottom of sash - part number 2903006.
- Available in 72" long length and will need to be cut to length to fit.
